Transcript context
…This is great. Nice job. We see this again and again. I can share a couple of other boards of ones that are in progress. We're also constantly adjusting the template so you can get to see a little bit more how people will edit their founding hypothesis from sprint to sprint. Mellow, who we were talking about, here's their first prototype, and here's their first scorecard. Lots of yellow for them. Maybe they're a little bit more likely to use yellow than red. Then, here's the edits to their founding hypothesis after the first sprint. You can kind of see in red, they're slightly changing the definition of their target customer from the first week, slightly changing the problem that they're solving, slightly changing the approach, slightly changing the competition. They've dialed in, they've gotten more crisp on who are we up against. They've gotten a little bit more crisp, just a tiny tweak, on what ... How do we explain this to people to get them excited about it? What's the differentiation? They sprint again, they prototype again. If we just jump down, and just looking at hypotheses, they learn a bunch. Now there's another slight tweak to that founding hypothesis. Week after week you're learning, but you're also really able to track exactly what is it that we learned and how does that affect our strategy. Okay, guys, this was incredible. I think we've covered the entire process. I love that you also covered the design sprint pieces, which isn't part of this book, but is such a core. Clearly these things are very connected and meant to work together. You go from here's the thing we should be building to how to actually test it. Let me ask you before we wrap up, is there anything else that you think is really important for people to know before they start trying this process at home? Is there anything you can point them to actually try this at home?…
